I keep returning to OP's images. Stunning, simply. Maybe he has to split his portfolio into RM and RF. The RM for the less-commercial but very artsy pictures and the ones with a clear concept (the industrial one for instance) on RF. Many star trails, but the one that needs its most, the Jodrell bank dish, has none. If the dish would have taken more close (cropped) with star trails, that would be a very good concept for telecom companies etc...

My personal favorite is the vintage airplane but I can't imagine what commercial product or service it could sell. Aviation? Travel? It's just beautiful and my guess is OP should think more mundane for what he uploads to RF stock.

wohooo - very nice pictures,... just wait and keep on uploading... the sales will come...

I understand that you are sweeping through your older files, but try to ad one of your latest shots per every old one... this way you will finish your old files, but you will have your recent work online as well... Some images might loose their relevancy while sitting on table for looong time... (- the buyers taste evolves, the recent look of image evolves...)

I also think that these photos have their charm if they are seen together, but those who look on the site retrive some of them only occasionally ...

Furthermore, with only an hundred of photos you never know what's going on sales. Personally I sold in early November many photos all at once. Then sales have suddenly stopped ... maybe suddenly resume.
